IMPROVEMENT IN TRAVELERS FOR SPINNING-RINGS.

Specification forming part of Letters Patent No. 136,719, dated March 1l, 1873.

To all whom it mag/, concern:

Be it known that I, JOHN GCULDING, of Worcester, in the county of yIfVorcester and State of Massachusetts, have invented certain Improvements in Travelers for Ring-Spinners, of which the following is a specification:

My invention consists in constructing a traveler used in ring-'spinning of a wire bail attached at each end loosely to two of the ordinary travelers, whereby it is made self-adj usting, and will wind the thread with a more uniform tension, as hereinafter more fully explained.

Figure 1 is a side elevation of a spindle and ring with my improved traveler applied thereto. Figs. 2 andf are top-plan views of the ring with my traveler' shown in different positions.

rEhe construction of the spindle and the ring A, being well known,. need not be described, they beir g Clearly shown in Fig. l.

As generally used the traveler consists of a small ring, e, clasped upon and fitting loosely over the top tlaiige of the ring A, through which the thread is passed, the traveler being carried around tli ring by the thread as the spindle revolves. With such a traveler the thread, where it is connected to traveler, is always at a fixed distance from the spindle, and

is constantly changing its angle in relation to the spindle or bobbin as the latter becomes filled with the thread, and this change of anw gle necessarily alters the tension of the thread,

thus making it more or less uneven.

To obviate this I make my traveler self-adjusting, and this I do by taking two of the ordinary travelers e and uniting-them by a small wire, f, which is looped to them at each end, as shown in the various figures of the drawing. This wire is bent in the form represented, so that it can swing to a greater distance toward and from the spindle, it being represented in its two extreme positions in Figs. 2

and 3. It should'be of such alength and form that when swung inward to its full extent, as represented in Fig. 3, it may touch the spindle. The swinging bail or wire f may be longer or shorter; but I have found by experiment that it works best when proportioned about as represented in the drawing, in which it will be seen that the space included between the two rings e at its extremities is about onethird ofthe circumference of the ring A, or a little less. It may be made shorter and bent up more in the form of a loop, and still operate, but not so perfectly, and `hence I prefer to make it as represented. Y

lt will be readily seen that when the thread is passed 'under the bail f the latter will readily adjust itself to the position or angle of the thread in reference to the spindle or bobbin that is to say, when it commences to wind the bail f will swing over near to the spindle or bobbin, as shown in Fig. 3; and as the latter becomes illed with thread it will gradually swing up to a vertical position, as shown in Fig. l, the tension of the thread and the centrifugal force tending to keep the bar f suspended free from contact with the bobbin. By this means I am enabled to Secure a more uniform tension on the thread, and to wind a bobbin varying from the smallest to the largest size possible with great ease and perfection. I am aware that a traveler has been made consisting of a single piece of wire or metal, having its -opposite ends resting in a groove on the inner face of the ring, and I do not claim Such; but Having described my invention, what I claim 1s- A traveler, consisting of the bar f secured loosely at its opposite ends to the rings e, substantially as and for the purpose set forth.
